Subject [jira] [Created] (MAPREDUCE-7120) Make hadoop consider wildcard host as datalocal
Date Thu, 05 Jul 2018 21:02:00 GMT
Brandon Scheller created MAPREDUCE-7120:

             Summary: Make hadoop consider wildcard host as datalocal
                 Key: MAPREDUCE-7120
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-7120
             Project: Hadoop Map/Reduce
          Issue Type: New Feature
          Components: client
    Affects Versions: 2.8.4
            Reporter: Brandon Scheller

Make hadoop consider wildcard host as datalocal.

This allows hadoop to treat "*" as data local. This allows remote filesystems to increase
performance by skipping retrys for data locality by returning "*" as the block host when the
filesystem is asked for the block location.
